Device for straightening and tensioning (forging) blade
(57) Abstract:The invention relates to a disk tool, and more specifically to a device for straightening and tensioning drive circular saw using propranol anvil and set correct, prokovich hammers, prepravnich lines. The device contains a set based propranol anvil connected to her guides with moving them with a carriage centering and height adjustable supporting the saw flange. Additional guides are located on both sides of and perpendicular to the main guides. The bearing support of the saw is made in the form of two slides, one slide contains a single point of support, and the second two equidistant from the line passing through the first support and additional parallel guides. Additional guides are located on the inverted U-shaped, movable on the height of the base. The invention allows to increase the objectivity and performance of the control flatness and tension of the drive, as well as the quality of the training blade. 1 C.p. f-crystals, 2 Il. The invention relates to a disk tool, such as woodcutting and canarium saws, and more specific the correct prokovich hammers, prepravnich lines.Edit - fix local and General shape of a disk with the purpose of giving him normative flatness. Tension - creating a normalized initial tensile stresses in the peripheral zone of the disc and compression stress in the Central and middle zones to improve dynamic stability of the disk during operation. The most common operation execution tension is the forging of the Central zone of the disk progulochnyy hammer on the anvil with two sides. Edit and forging saws are produced in their manufacture, as well as retraining drank in enterprises operating circular sawing machines.The known device for straightening and forging circular saws, made in the form propranol anvil, the Foundation under it, set the right and prokovich hammers lines, [1, s 281]. However, such devices have a major drawback - the high complexity of the preparation of drinking large diameters, for example, more than 700 mm Weight these saws reaches several tens of kilograms and working at the location of the saw blade on an anvil and striking it with a hammer is necessary to continuously maintain the saw by hand.However, the process of editing and forging is usually accompanied by multiple control flatness and tensioning of the blade, marking the defective places for their subsequent elimination. This saw is removed from the above-described device and transferred to the device to control the flatness, tension (degree of forging) drive or control operations are performed using prepravnich lines when installing the saw in the horizontal and vertical positions on a special workplace. The process of editing and forging all drank large diameter long. For example, saw blades with a diameter of 1000 mm he is 2-4 hours to prepare one saw. The need for periodic removal of the saw from the primary workplace of preprava, you move it to another workspace to perform control operations and return to your previous job, significantly increases the volume of work on the edit and the forging of the disk.The invention is directed to reducing the complexity of manual transpore conditions of the control operations.The invention consists in that in the known device for straightening and tensioning of the blade, including the established on the basis of propranol anvil and announced to her guides with moving them with a carriage centering and height adjustable supporting the saw flange, perpendicular to the rails with both sides installed additional rails with supports in the form of two slides, one slide contains a single point of support, and the second two equidistant from the line passing through the first support additional parallel guides.Additional guides are located on the inverted U-shaped, movable on the height of the base.The presence of additional rails with supports in the form of two sliders provides the ability to control the flatness and tensioning of the blade without removing it from the supporting flange after editing and forging. An inverted U-shaped, floating, height-base provides the passage through it of the carriage centering and supporting flange, and the rise of saws on the supports when assessing its flatness and tension.In Fig. 1 shows a device, spurenelemente carriage 4 with the axis 5 and the supporting blade 6 height adjustable flange 7, the guides 8 to move the sliders 9 and 10 with the supports 11 and 12, an inverted U-shaped base 13, a counter 14, a handle 15 for regulating the base 13 in height.Device for straightening and forging works as follows.Saw 6 is put on the axle 5 and is installed in a horizontal position on the supporting flange 7 with the elastic strip. Produce initial configuration of the flange height. The carriage 4 is shifted to the right to the treated place saw was on the anvil 2. Rotating the saw 6 around the axis 5 and moving the carriage 4 along the guide rails 3 "left-right" handle with a hammer all marked on the saw. Then, the carriage 4 is shifted to the left and enter in the U-shaped base 13 so that the center of the saw 6 was on the line passing through the bearing 11 and the middle of the distance between the supports 12. Moving the sliders 9 and 10 along the guide rails 8, provide the position of the supports 11 or 12 at the circumference, spaced from the circumference of the tooth saws 5-10 mm With handle 15 raise the base 13 and set the saw 6 on the supports 11 and 12. In the slot axis 5 invest propranol line whose length is equal to the diameter or radius of the saw, and lightly touch the surface of the saw. The calibration line should be located to perido disk saws and propranol ruler characterize the flatness and tensioning of the blade. Rotating blade 6 about the axis 5, evaluate the flatness and tension of drive in various diametral and radial sections. Using a special pencil mark on the blade places that require processing on the anvil 2. After assessing the blade and markup on it defects by using the handle 15 is lowered base 13, the supports 11 and 12 and set the saw 6 on the supporting flange 7 with the elastic strip. The carriage 4 with the saw 6 is shifted to the right to the treated site was on the anvil 2. The process of saws and control of its flatness, the tension leading up until the training quality saws will not comply with regulatory requirements.The use of the proposed device for straightening and tensioning (forging) blade reduces the complexity of manual work, to increase the objectivity and performance of the control flatness and tension of the drive, focus attention on the process of editing, forging and improve the quality of training blade.Sources of information

Astroline and announced to her guides with moving them with a carriage centering and height adjustable supporting the saw flange, characterized in that the perpendicular guides with both sides installed additional rails with supports in the form of two slides, one slide contains a single point of support, and the second two equidistant from the line passing through the first support additional parallel guides.2. The device under item 1, characterized in that the guides are located on the U-shaped, movable on the height of the base.
FIELD: metal working.
SUBSTANCE: hard alloy matrix has casing, bushing pressed in the case and hard alloy insertion. Bushing has multifaced hole. Hard alloy insertion is composed by several sections made in form of trapezoidal-section prisms which have cut angles at their non-working edges. Number of sections corresponds to number of faces of item to be headed. Cuts of angles are made symmetrically to faces of working edge. Slits are made in several places of multifaced hole bushing at the ponts where faces cross each other.
EFFECT: improved resistance of matrix; simplified assembly.
